Portfolio import

Your whole portfolio, in minutes not weeks.

onOffice, Propstack, FLOWFACT, EXPOSÉ, a plain CSV – they all export OpenImmo. You upload the file and WOHNO turns it into ready-made drafts: fields mapped, images loaded, energy certificate detected. On the next export, WOHNO only reconciles what changed – nothing imported twice.

Four guarantees

Import without the rework

From upload to the last image, WOHNO does the busywork – while protecting whatever is already live.

Upload that understands every format

Drop in your OpenImmo container as a ZIP or the bare XML – up to 50 MB, up to 200 objects per file. Images bundled inside are loaded straight away, with progress running live.

Smart mapping with fallbacks

Address, rent, areas, amenities and energy certificate land in the right field automatically – including fallbacks for exports that tuck values away in unusual places. Unknown fields are logged, never dropped.

Delta sync instead of duplicates

On the second import, WOHNO recognises every object by its reference and updates only what changed. Unchanged images are skipped – no duplicate chaos, no re-uploads.

Aktive Inserate sind geschützt – kein unbeabsichtigtes Abhängen.

Safe deletion protects active listings

When an object drops out of the export, it's archived instead of hard-deleted – applications and appointments stay intact. Active listings never go quietly offline; they're flagged for review instead.

Before / After

End the retyping marathon

Maintaining a portfolio today means building spreadsheets, retyping fields, uploading images one by one, hunting duplicates. WOHNO turns all of that into a single upload.
